| Popis: | A study was made of the sintering of bronzes with varying amounts of phosphorus, up to 1%. The optimum phosphorus content, at which pores do not decrease in size or become blocked and no crack formation occurs, was found to be 0.3%. To enable sintered filters to be attached strongly to other components, the portions of filters used for fastening should be made from finer powders. The feasibility is demonstrated of producing filters composed of several layers of powders differing in particle size; the pouring of each powder fraction is followed by vibratory densification in the mold, sintering being performed after the whole multilayer part has been built up. Filters produced by the methods described are characterized by satisfactory air permeability and strength. |
